Solo mining pool: bitcoin, bitcoin cash, litecoin, dogecoin and pepecoin
- 99% / 1%per block found
- 0accounts, minimums or waiting
- 5coins on our own nodes
You mine on your own luck, on our own nodes. Find a block and 99 percent of the block reward plus the transaction fees goes straight to your address, inside the block itself. The pool keeps 1 percent. Find no block and you earn nothing.

Odds, block reward and records per chainThe figures come straight from the pools and refresh every minute. Enter your payout address to see your own miners. No account needed.
Best share is the highest difficulty your miner has found. If it beats the network difficulty, you have a block.
Risk warning (EU MiCA): Investing in crypto-assets is risky (EU MiCA). You may lose your entire investment.
Connect
- 1Pick your coin and port: your own miner or rented hashrate.
- 2Enter your address and copy the username.
- 3Put the port and username into your miner, with x as the password. There is no account.
By connecting your miner, you enter into an agreement with us: a 1 percent fee on a block found, no other costs, no fixed term, and you can always stop free of charge. As a consumer, you have a 14-day right of withdrawal. Read the pool terms in our terms and conditions.
Miners connect through a server in Frankfurt: low ping across Europe, and the nodes themselves cannot be reached directly from the internet.
Your own miners, from Bitaxe to ASIC

Rented hashrate (NiceHash, MRR, HashStrike)
stratum+tcp://pool.cryptocodes.eu:3339
The rental ports start at a high difficulty because rental platforms require it. A Bitaxe will almost never reach a share there, so point your own miners at the regular port.
Starts with L, M or ltc1q.
Starts with D, A or 9.
Starts with P. Fill it in and you mine pepecoin with the same work; leave it empty and you mine litecoin and dogecoin only.
That way each miner shows up separately in the live stats.

Addresses are checked only in your browser, with the same rules as the pool. Your username appears only once everything is valid.
Litecoin, dogecoin and pepecoin run on Scrypt and are mined together: the same work counts on all three. You need a Scrypt miner for this; a SHA-256 miner will not work here.

What the pools run on
No data centre: our five nodes and the pools all run on a single mini PC.
- Machine
- Blackview MP100, mini PC
- Processor
- AMD Ryzen 5 7430U, 6 cores and 12 threads
- Memory
- 32 GB DDR4: 16 GB as standard, upgraded with another 16 GB
- Storage
- 2 TB NVMe SSD
- Software
- umbrelOS 2.0
The nodes don't add up exactly to the total, and that's expected. Memory: each node's figure includes cache (data Linux has read and releases as soon as something else needs the space); in the total, that cache counts as free. Disk: the total covers the whole drive, including umbrelOS, the pools and the other apps; each node shows only the folder with its own chain.
Why this is safe
Pruned, just as secure
Every node checks every block and every transaction itself, just like a full node. The only thing it doesn't keep is old blocks, and it has already checked those.
Shielded
Miners connect through a secured server in Frankfurt. The mini PC itself cannot be reached from the internet.
Monitored
If a node hangs, the watchdog restarts it within a few minutes and alerts us straight away.
Hourly backup
Encrypted, on a separate drive.
Tested
Automated tests of the merged mining pool against the real nodes, a script that re-checks the 99/1 split, and tests from outside with our own miners and test addresses.

How it works
- Payout
- Almost daily, small amountOnly when you find a block
- Size
- In proportion to your share of the poolThe whole block reward plus that block's fees
- Spread
- Low: the return is predictableVery high: nothing for a long time, then everything at once
- Suits
- Anyone who wants a steady monthly amountAnyone who accepts that nothing may ever come
Straight from the block
The block your miner finds pays out itself: 99 percent to your address and 1 percent to the pool, as two separate payouts. The pool never holds your coins, so there is no minimum and no waiting for a payout round.
Litecoin, dogecoin and pepecoin separately
One share can yield a litecoin block, a dogecoin block, a pepecoin block or several at once. Each block pays out on its own chain, to the address you gave for that chain.

These amounts come from the protocol itself. Bitcoin and bitcoin cash both halve around April 2028, litecoin at block 3,360,000, expected in mid-2027. The dogecoin reward has been fixed at 10,000 per block since 2015 and no longer halves; pepecoin's has also been fixed at 10,000 since block 600,000. Transaction fees in a block come on top and vary from block to block. Network hashrate and prices are deliberately left out of this table: they change daily.
The bitcoin and bitcoin cash pools run on existing open-source pool software. Litecoin, dogecoin and pepecoin run on the original nodes of those networks. Because existing pools can only pay one address when merge mining, our pool builds a separate block for each miner on top of them. You don't have to take our word for the payout: it is written into the block itself.

How to verify a payout
- Look up the block in a block explorer by its height.
- Open the first transaction in that block: the coinbase, which creates the new coins.
- It contains two payouts: 99% of the block reward plus transaction fees to the address of the miner who found the block, and 1% to the pool. Lines without an amount are technical data.
No block has been found on these pools yet. Once one is found, here's how to check it.
Who this suits and who it does not
Your chance per block is your own hashrate divided by the whole network's. A home miner up against a network measured in exahashes waits thousands of years on average. Small miners have still found blocks, but don't count on it as income.
Go ahead if
- • You own a Bitaxe, NerdQaxe or similar small miner and want to run the odds yourself
- • Your hardware is running anyway, for the heat for instance
- • You want to see a block found and broadcast, not just a balance ticking up
- • You can go months or years without a payout and not mind
Better not if
- • You need the return to pay the electricity bill
- • You want a predictable monthly amount — pick a shared pool instead
- • You are buying hardware specifically for this and counting on earning it back
- • You expect a bigger miner to make the outcome certain; it only shortens the expected wait
Frequently asked questions
Yes, on port 3333 for bitcoin or 3334 for bitcoin cash. Any miner that speaks stratum can take part. Litecoin, dogecoin and pepecoin need Scrypt hardware; a SHA-256 miner will not work there.
Yes, that is what the rental ports are for: 3338 for bitcoin, 3337 for bitcoin cash and 3339 for litecoin with dogecoin and, if you like, pepecoin. Use your own address as the username in your rental order. Do expect nothing back: rental costs money by the hour, and whether a block comes of it is chance.
Over the long run the expected return is roughly the same; the difference is the variance. A shared pool often pays a small amount, a solo pool almost never pays a large one. Expect nothing and treat a found block as a windfall.
Solo mining carries no guaranteed return. Your chance of a block depends on your own hashrate against that of the whole network, and electricity costs keep running whether you find a block or not. The pool is a technical service, not an investment product.
